Another Belstaff "real or fake" tread

Bought this Belstaff Roadmaster in a secondhand shop today for 300 USD.

However a friend of mine suspected that it was a fake!

What do you think?

It is definitely really waxed, and the buttons etc looks good. My only concern is that the jacket is really light and the liner does not go all the way down (no liner in the arms and on the bottom). The liner (which I believe is in a odd colour), along with overall build quality also seems rather cheap. Along with this there is no buttons on the inside to pop in a liner/gilet and the tag does not say where it was produced.
